Please excuse the delay:
1) Yes and no. Part of their success comes from your own will and perception of the result. Yet, your perception would change if you at least gave them a chance to work. Instead of prematurely concluding that the result is bad, you should instead decide to withhold conclusions until you have more evidence.
Since your problem comes solely from feeling, then it would make sense to directly practice this. The best time to do this would be right after your meditations. Sit and focus on a chakra, such as the 6th, and put yourself in a passive state. Try to feel the chakra: Try to judge its shape, quality, status, and other features.
This is no different than how you feel a physical object. It is a feminine and passive activity. It is ok if you have thoughts in your head, too, but try to calm them and focus on the sensation of the chakra itself.

As far as enervation, this may be uncomfortable, but it should not be an obstacle. Yoga will definitely help heal and calm this. Similarly, yoga or pranayama directly stimulate the associated chakras, so it is impossible to claim that nothing happened.
For example, the lunar breath activity directly improves your intuition, sensations, astral senses, and so on. This would be great for you: https://www.satanisgod.org/www.angelfire.com/empire/serpentis666/Kumbhaka_Lunar_Breath.html
You will feel the energy move to your head, right where the 6th chakra is.
2) You can visualize anything, but it is best to start with something simple. Use this:
3) The opening procedure is like a one-time activity that initially restores activity to a dormant chakra. Then, you continue with daily empowerment so that the chakra stays open and continues to strengthen and improve.
Each day should have some sort of cleaning and empowerment for all the chakras, but the chakra opening goes in the specific sequence. If you did not open a chakra yet, then you can wait on the empowerment, but otherwise chakras should always be empowered and cleaned daily.
Spinning is an example of empowerment because you are simply willing the chakra to spin faster. If this is hard for you, then I would instead say to either use mantras or practice breathing in white-gold energy directly into the chakra.
Once you finish the chakra opening, you do not have to continue the same opening procedure, but you should maintain another empowerment activity.
4) Due to your situation I had made the call to advise you on using Fehu, however that could've been premature if your confidence or power was not strong enough. I agree with your decision here, and support this. Doing changes directly to your soul is much easier and directly evidenced, as opposed to doing work on the world around you.
I hope this answered everything.
